86 LANDSCAPE GARDENING, 



Hardy Climbing Shrubs.* 



The part that hardy climbers play in the landscape or 

 ornamental art is often very important. As a summer 

 covering for verandas and arbors nothing possesses so much 

 natural beauty. They supply the beautiful green so pleas- 

 ant to the eye, and by constant evaporation of moisture from 

 their leaves produce a cool shade that no artificial material 

 can supply. Some of them possess most beautifully cut or 

 shaded foliage, while others produce most beautiful flowers, 

 and when once planted they grow on for many years with but 

 little care. Some of them, like the wistaria, Aristolochia, 

 Actinidia, bittersweet, etc., will twine about large pillars 

 or other supports, some will support themselves to brick or 

 stone walls by their suckers, while many, like the clematis, 

 etc., require the support of the trellis, the single wire, or 

 the wire netting. 



If grown too abundantly or trained too closely to the 

 building, vines often render the dwelling damp and un- 

 healthy and cause rapid decay of the woodwork. 



As to cultivation, they require the same care and fertility 

 of soil as recommended for upright shrubs. Fig. 48 shows 

 a vine-covered cottage in June, Fig. 49 the same in April. 



PRUNING OF CLIMBERS. 



In addition to the pruning required to keep climbing 

 vines within proper limits, which can be largely done by 

 pinching and light clipping during the summer, they 

 require in some cases the cutting back of the old wood of 

 the laterals in order to produce fresh clean shoots and
